| Question | Answer |
|---|---|
| Axial Subdivision | Head, Neck, Torso (or trunk and subdivisions) |
| Appendicular Subdivision | Upper extremity and subdivisions Lower extremity and subdivisions |
| Set Point | Ranges that can change with the changing circumstances the point of homeostasis that the body uses feedback loops to maintain |
| Homeostatic Control Levels | Within Cells (Intracellular), Tissue or Organ (Intrinsic Control), Organ to organ (Extrinsic Control) |
| Subatomic particles in atoms | Protons (p*) Neutrons (n^0), Electrons(e^-) |
| Metabolism | All chemical reactions in body cells: Catabolism- Chemical reactions that break down molecules and release energy Anabolism- Chemical reactions that join molecules forming more complex molecules |
| Organic Molecules | Molecules that contain C-C or C-H bonds |
| Carbohydrates | Organic compounds containing: carbon, hydrogen, oxygen (sugars and starches) |
| Lipids | Water-insoluble organic molecules: Major roles- Energy source, structural role, Integral parts of cell membrane |
| Proteins | Most abundant organic compounds Chainlike polymers of amino acids held together by peptide bonds forming polypeptides |
| Lysosomes | Organelle of the cell that acts like digestive system. Enzymes digest the protein of unneeded or defective cell parts |
| Cells Connections (how do cells hold to each other) | Desmosomes- fibers on outer surface interlock with each other in spot (spot welds) or belt points (encircle whole cell) Gap Junction- Membrane channels adhere to each other Tight Junction- Joined by "collars" that molecules cannot permeate |
